What are the advantages of using a cob packaged LED display? A cob display is a led display made using cob packaging technology, but at present, the cob packaging technology is not very complete. Cob packaging led manufacturers, as far as led display companies are concerned, if the current production system is transferred to cob packaging, led display manufacturers will experience a new round of "exchange", because generally speaking, LED displays are packaged by SMD There are essential differences between SMD and COB. Cob packaging has fewer steps, low cost, and strong protection; SMD packaging is cumbersome, devices exposed, and high cost.

　But between the two, SMD packaging is currently used more and the technology is relatively complete, while the cob packaging technology has only been tapped in recent years, and the technology is in a state of need for improvement. Therefore, the current situation is that cob packaging requires perfect technology, high research and development costs, and a lot of energy. At the same pitch, the price of cob packaged led display will be 10-20% higher than that of SMD packaged led display.

　　 Moreover, SMD packaged led display manufacturers will receive COB package patents and other restrictions, even if they want to implement corporate transformation, there will be certain difficulties. At present, there are not many manufacturers of cob packaging leds. Except for Lehman and Cedar, Dayuan Intelligent is a rising star in the field of cob display. The cob packaged led display has a variety of incomparable advantages over the small pitch of SMD packaged leds, such as: effective suppression of moiré, ultra-fine pitch below 1.0mm, ultra-fast heat dissipation due to small thermal resistance, and the device can not drop lights when closed. The cob led display can be said to be an evolutionary version of the small pitch of the LEDs. Under the premise of inheriting the small pitch of the LEDs, it also has the advantages of its own packaging method and is unique in the field of precision displays.
